Explanation: 

Detailed explanation-1: -Light does not travel in a straight path. It travels as a wave. However as the wavelength is very small, it looks like it travels in a straight line. Also when light travels from one medium to another, it bends.

Detailed explanation-2: -Light travels as waves. These are transverse waves, like the ripples in a tank of water. The direction of vibration in the waves is at 90° to the direction that the light travels. Light travels in straight lines, so if you have to represent a ray of light in a drawing, always use a ruler.
